cpu fan not turning on

post #1 of 7
Thread Starter 
I'm trying to get an old celeron box i found in my basement working again. Unfortunately, i can't get the cpu heatsink fan working.

The power supply is definitely good, and the fan works on other motherboards just fine. (It's just a stock heatsink.) I checked and the fan is getting exactly 1 volt. Any ideas? (I don't have any memory in yet, but that shouldn't affect the fan, right?)

thanks,
Mark

Take Out the Fan, Clean Out those dreaded Dust bunnies, Give it a Few Spins with your hand, check that nothing could be stopping it from spinning. Put it back in the Computer, check all your connections and try again

well i'll rip some ram out of another box just to try that... The fan WORKS on other mobos though. and other known good fans don't work either. Is 1 volt correct? it's EXACTLY one volt at the three-pin.
